you say that, you know, conspiracy theorists came up with this idea that george w. bush, bush 43 as he's known in this country, and tony blair knew there were no weapons of mass destruction in iraq but invaded anyway. your book says that's bunk. >> yes. the book really says that the intelligence agency simply got it wrong. the politicians, talking particularly about here in london, thought the weapons were there, and they thought it because the intelligence agencies told them they were. so i really focus on trying to understand why mi6 got it wrong over those iraqi weapons of mass destruction. and incidentally, a lot of that british intelligence was vital in the american case for war. but they simply were being told things by their agents in iraq which were not true, and the quality control, the checking on that information simply failed. people were saying this is here, that's here, and they believed it. the checking simply didn't work. and that played a key role in the case for the war. and especially in britain. i think it has done a lot of harm to the reputation
